Answer:
a.) The Null Hypothesis can be said to be: [tex]H_{0} : \mu \leq 1 gram[/tex]
  The Alternate Hypothesis can be: [tex]H_{a} : \mu > 1 gram[/tex]
For b.) and c.) please see explanation below
Step-by-step explanation:
a.) The Null Hypothesis can be said to be that the 3 quart container contains less than or equal to 1 gram of fat
[tex]H_{0} : \mu \leq 1 gram[/tex]
Therefore the Alternate Hypothesis can be that the 3 quart container contains more than 1 gram of fat
[tex]H_{a} : \mu > 1 gram[/tex]
b.) In Type I Errors  the given Null hypothesis is rejected when in fact it is true.
In this situation the Type I error would be that the statement that the 3 quart container contains less than or equal to 1 gram of fat is rejected when it is actually true.
c.) Type II errors are those where the Null Hypothesis is false but is not rejected.
In this situation the Type II error would be that the statement that the 3 quart container contains less than or equal to 1 gram of fat is false but it is not rejected.
